Introduction

You’re in your mid-to-late 40s. Life is busy but manageable. And then, seemingly out of nowhere, anxiety shows up or gets dramatically worse. Maybe it’s waking you at 3am with a racing heart and a spiral of thoughts you can’t shut off (been there!). Maybe it’s an edginess during the day that sits just below the surface and it makes you startle-ready (yup). Or maybe you’ve started avoiding things you used to handle easily. It could be that you’re having moments that feel almost like panic attacks and you have no idea why.

You’ve googled your symptoms and you’re wondering if you’re falling apart, right? You’ve possibly been told “you have a lot going on.” Possible you’ve had an antidepressant suggested. All this, with no one mentioning the word perimenopause.

Here’s what I want you to know: you are not losing your mind. You are quite possibly in perimenopause. And the anxiety, the sleeplessness, the mood volatility, even the super itchy ears – these are not character flaws or signs of psychological weakness. Truly, they aren’t. They are very real neurological events. And once you understand what’s actually happening, a lot of things begin to make sense.

What’s Actually Happening in Your Brain and Body

Perimenopause is the transition period leading up to menopause, which can begin anywhere from the late 30s to the mid-50s. It is commonly understood as a reproductive shift. What’s less commonly discussed is that it’s also a significant neurological event. But I didn’t know perimenopause was a thing at all. So, I’m here to shed some light on what’s really going on. 

Estrogen isn’t just a reproductive hormone. It plays a major role in regulating serotonin, dopamine, and GABA. These are the neurotransmitters that govern mood, your sense of calm, sleep, hair and skin condition, and emotional regulation. Estrogen levels begin to fluctuate and eventually decline during perimenopause. So, your menstruation and those systems will all fluctuate with it. The result can look a lot like an anxiety disorder.

Progesterone, another key hormone that drops during perimenopause, has a naturally calming, anti-anxiety effect on the brain. So naturally, when it decreases, many notice a significant increase in anxiety, irritability, and difficulty sleeping. This is because the neurochemical buffer that was quietly doing its job in the background is no longer reliably present. Some days the hormone might be higher. Other days it’s really low, which is why sometimes you may feel like yourself and other days you feel inhabited by an alien. 

Add to this the cortisol dysregulation that often accompanies perimenopause and you feel cooked. Cortisol affects your stress response and makes it harder to settle down after activation. This will mena you have a nervous system that is genuinely running differently than it was five years ago. This isn’t in your head. It’s in your body.

The Symptoms That Often Get Missed or Misdiagnosed

Perimenopausal anxiety doesn’t always look the way we expect anxiety to look. Some of the most common presentations I see in clients include:

• Waking between 2-4am with a racing heart, a sense of dread, or just an inability to get back to sleep – even when nothing is particularly wrong
• New or intensified panicky symptoms: heart palpitations, shortness of breath, a sudden sense that something is very wrong
• Increased irritability and a shorter fuse – the “I can’t believe I just said that” kind of reactivity that feels intensely out of proportion and out of character
• Difficulty concentrating or a sense of mental fog, which can compound anxiety (“What’s wrong with me?” becomes its own spiral)
• A low-level hum of unease that doesn’t attach to anything specific
• Heightened sensitivity to stress – things that used to roll off you now feel genuinely overwhelming, which leads to to avoid things (anxiety’s key action)
• Depressive episodes or emotional flatness mixed with periods high-anxiety or agitation

What makes this particularly confusing is that these symptoms often arrive in waves because they’re tied to the hormonal fluctuations. You might have stretches of feeling completely fine, like I mentioned before. Then a week that feels like a crisis. That inconsistency leads many women to doubt themselves, feel like they’re losing their mind, and to underreport what’s actually happening.

Why This Often Gets Missed in the Doctor’s Office (and the Therapy Office)

The average time between when a woman first experiences perimenopausal symptoms and when she receives an accurate explanation for them is distressingly long. There are a few reasons for this.

First, perimenopause is underdiagnosed as a category. Like I said, many of us didn’t know it was a thing. I just thought I was entering menopause because I had a lot of this kind of dysregulation. Additionally, many healthcare providers are not well-trained in recognizing the psychiatric presentation of hormonal transition. Symptoms are often treated in isolation from one another. For instance, the anxiety is addressed as situational anxiety. The sleep disruption as a sleep hygiene problem. The mood changes are said to be part of depression – without anyone connecting the dots to where they’re coming from.

Second, because certain aspects of perimenopause can begin before periods become too irregular, many women (and providers) don’t yet see the obvious signal that hormonal change is underway. So if you’re still having relatively regular periods, “perimenopause” may not be on anyone’s radar.

Third – and this one matters a lot – women in their 40s often do have a lot going on and end up being a forgotten focus. Aging parents, career demands, relationship transitions, children leaving home, etc. It is very easy to attribute anxiety to circumstances and miss the underlying hormonal driver. Both can be true simultaneously, but only addressing the circumstances while the neurochemical piece goes unrecognized means real relief stays out of reach. Consequently, women believe and are told to simply manage life better. And that sucks. 

What Actually Helps

There’s no single answer here, because perimenopausal anxiety is a layered experience that deserves a layered response. But here are the things I find genuinely move the needle:

Getting an accurate picture of what’s happening hormonally. This means working with a provider who is knowledgeable about perimenopause; ideally someone who practices integrative or functional medicine, or a gynecologist with a focus on menopause. Hormone testing has limitations, but understanding your hormonal landscape is still a valuable starting point. And, of course, it’s not covered by most insurance plans – so it’s costly but SO valuable. Keep in mind that bloodwork is one snapshot. Our blood levels change daily – so, if you can afford the cost – it might be helpful to get bloodwork drawn monthly for a bit to see what the patterns might look like. 

Nervous system support. Because perimenopausal anxiety is in part a nervous system dysregulation, approaches that work directly with the nervous system, like somatic therapy, breathwork, body-based regulation practices, etc. can be particularly helpful. Cognitive approaches alone often fall short here, because this anxiety isn’t primarily cognitive in origin – it’s a physiological response to the body changes we listed before. 

Sleep as a non-negotiable priority. The sleep and mood disruption of perimenopause were my first clues. Sleep is both a symptom and a driver of anxiety. Working on sleep hygiene, addressing the 3am waking pattern, and sometimes addressing the hormonal contributors to disrupted sleep directly can make a significant difference in daytime anxiety levels. Whether it’s getting a sleep study, changing sleep hygiene factors, or sleeping in your own room if you have a ‘snoring partner’ have to be considered. 

Therapy that understands the whole picture. If you’re working with a therapist who is treating your anxiety as purely a thinking problem, without any acknowledgment of the hormonal and neurological context – you’re missing a significant piece of support. Therapy can be enormously helpful during perimenopause, but it needs to hold the full picture of what’s happening in your body, not just your mind.

Self-compassion for the timeline. Perimenopause is a transition, not a destination. It doesn’t last forever but it can last a very long time – we’re talkin’ years – and that deserves acknowledgement. You’re not broken, love. You’re in the middle of a significant neurological and hormonal shift that most of our culture – including most of medicine – still significantly underserves.

You Don’t Have to Navigate This Alone

The anxiety and mood changes of perimenopause are real, they are significant, and they are treatable. Treat yourself like you would a friend, and get the support that understands the whole picture – not just the anxious thoughts, but the nervous system underneath them, and the hormonal context driving the whole thing.

I work specifically with women in midlife, and I’ve been through this myself. It’s vital to understand that the intersection of hormonal transition and mental health is something to take seriously and even sacredly. If what you’ve read here resonates, if you’ve been wondering whether something more than “stress” is driving what you’re feeling, I’d be honored to talk with you.

You’ve been managing this quietly for long enough.
